Basic definitions to start- Waves 0.0 / 5 ? PhysicsWavesASAQA Created by: Lilli1997Created on: 03-06-15 12:13 What is a progressive wave? A wave whose oscillations travel. This type of wave transfers energy. 1 of 16 Define frequency. The number of wave cycles that pass a point each second. 2 of 16 What is frequency measured in? Hertz (Hz) 3 of 16 Define amplitude. The maximum displacement of a particle in a wave from its equilibrium position 4 of 16 Define wavelength. Distance between two adjacent points in phase in a wave 5 of 16 Define period. The time for one complete wave (cycle) to pass a point 6 of 16 What is a transverse wave? Waves whose oscillations are perpendicular to the direction of energy transfer 7 of 16 What is a longitudinal wave? Waves whose oscillations are parallel to the direction of energy transfer 8 of 16 When two waves are half a wavelength apart they are in... anti phase 9 of 16 What do you call it when the oscillations of a transverse wave are restricted to one plane? polarization 10 of 16 Why is polarization used in sunglasses? reduces glare 11 of 16 When two waves with similar properties but travelling in opposite directions meet in phase you get... constructive interference 12 of 16 When two waves with similar properties but travelling in opposite directions meet in anti phase you get... destructive interference 13 of 16 Define stationary wave. Fixed pattern of vibration where no energy is transferred along the wave 14 of 16 A point on a stationary wave where there is no displacement is called a... node 15 of 16 A point on a stationary wave where there is maximum displacement is called a... antinode 16 of 16
